LCA‐based evaluation of greenhouse gas reduction potentials of carbon/carbon wheel brakes for medium‐haul aircraft

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Air transport is expected to substantially grow in the next decades, presenting a significant challenge for the aviation industry to reconcile this growth with the need to mitigate climate change by reducing greenhouse gas (GHG) emissions. A viable strategy for diminishing aviation emissions involves reducing aircraft fuel consumption, which ...

Only One Percent of Important Shark and Ray Areas in the Western Indian Ocean Are Fully Protected From Fishing Pressure

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Delineation of Important Shark and Ray Areas (ISRAs) In the Western Indian Ocean was enhanced by the verification and incorporation of unpublished records. Even with this expanded dataset, ~99% of ISRA coverage fell outside of fully protected, no‐take MPAs.

Bifurcation Analysis of Nose-Landing-Gear Shimmy with Lateral and Longitudinal Bending [PDF]

Journal of Aircraft, 2010
This work develops and studies a model of an aircraft nose landing gear with torsional, lateral, and longitudinal degrees of freedom. The corresponding three modes are coupled in a nonlinear fashion via the geometry of the landing gear in the presence of a nonzero rake angle, as well as via the nonlinear tire forces.

GL‐algebras in positive characteristic II: The polynomial ring

Proceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.
Abstract We study GL$\mathbf {GL}$‐equivariant modules over the infinite variable polynomial ring S=k[x1,x2,…,xn,…]$S = k[x_1, x_2, \ldots, x_n, \ldots]$ with k$k$ an infinite field of characteristic p>0$p > 0$. We extend many of Sam–Snowden's far‐reaching results from characteristic zero to this setting.
